A second confirmed design contract for Wärtsilä's new series of arctic platform supply vessels has been signed. This latest order is for a multi-purpose platform supply vessel (MPSV) being built by Tersan Shipyard in Turkey on behalf of U.S.- based Tidewater Inc, the leading provider of offshore service vessels to the global energy industry. The vessel will be operated by the Norwegian Troms Offshore Supply Group, a 100%-owned subsidiary of Tidewater. There is an option for further three similar vessels. A key element in the award of this contract was Tidewater's requirement for a compact design yet with a high deadweight giving maximum cargo capacity. Operational efficiency and reduced fuel consumption were among the other reasons why the Wärtsilä solution was selected.
